When I'm trying to search for a Java class with Ctrl-shift-T (Open Type popup), Eclipse freezes when I'm typing 1 character. It usually takes about 8 seconds to 'unfreeze', but sometimes it won't come back at all.. When it freezes, I see that the eclipse process takes about 1Gig of mem and the CPU is about 100%!

I've tried creating a new workspace, adjusting the eclipse.ini (perm size, different memory values), starting with -clean and at last reinstall the whole IDE. Nothing helps..

My eclipse.ini:

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.100.v20110505
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
768m
--launcher.defaultAction
openFile
-vmargs
-server
-Dosgi.requiredJavaVersion=1.5
-Xmn128m
-Xms1024m
-Xmx1024m
-Xss2m
-XX:PermSize=128m
-XX:MaxPermSize=128m
-XX:+UseParallelGC
-Djava.library.path=/usr/lib/jni

I'm using the following plugins: JRebel and m2e. I'm desperate for a solution because this problems causes me a great deal of time loss.

System: Ubuntu 12.04 LTS 64 bit, 4GB mem, Intel core i7 860 @ 2.8 Ghz.

Hope somebody knows a solution. Thank you for your time.

I had the same issue... i think. It's related to this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=384315

It's an issue with GTK. try to remove libgail18. The issue is resolved, So I think it will be in the next maintenance version.

I did not want to remove libgail18 package entirely, because there are too many things that depend on it, so I simply renamed /usr/lib/x86_64-linux-gnu/libgailutil.so.18.0.1 to libgailutil.so.18.0.1.OFF.

This makes Eclipse fast again and gives me the option to re-enable the library if I need it for something else.

I suffer from the same problem where Open Type hangs Eclipse for prolonged periods, typically around 2 minutes making Eclipse unusable. This only happened about 2 months after using this machine daily as a development machine.

Unfortunately I haven't managed to get to the bottom of it either. Of note I'm also running an Ubuntu 12.04 LTS 64 bit machine (8GB memory, Intel® Xeon(R) CPU X3450 @ 2.67GHz × 4).

java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.1) (6b24-1.11.1-4ubuntu3) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

I've also tried the Oracle JDK, 1.6.0.30. It didn't help.

I've tried installing many different versions of Eclipse:

  • 3.6
  • 3.7 (From Eclipse.org & installed via apt)
  • 4.2
  • Spring Source All of which suffered from the same problem.

Trashing my .workspace & .eclipse directories and having no custom plugins didn't help.

What did help was creating a new user account on my box. Unfortunately this also only worked for about a month. This does give me hope that there is some cache or file in my home drive that I can could delete to work around the problem, but I haven't found it. I'm now faced with creating another user or getting to the root cause of the issue.

  • Hmm oke, so creating a new user helps, didn't know that.. Still hoping for a better, permanent solution though:)! So if you come accross some solution, please post it in this topic.

When faced with similar issue on Windows, adding clean option to 'startWCToolkit.bat' helped. I'm sure there should be similar script on Ubuntu too. An excerpt of file:

"rationalsdp.exe" –clean   -showlocation -debug
